CNC machines are one of the important tools in the industry, the accuracy of their work is very important in manufacturing parts and other industrial processes. For this reason, CNC machine calibration is very important and should be done regularly. In this article, we would like to examine the steps and tools of calibrating the CNC machine and the importance of this issue
Importance of CNC machine calibration
CNC machine calibration is one of the best methods to detect and correct errors, maintain design accuracy, tool accuracy and repeatability of CNC machines. In other words, this work helps to maintain the highest quality standards of the manufactured product and ensures that all the tools can do their work without causing any accidents. In other words, it can be said that calibrating the CNC machine is one of the most important things you should do to maintain this machine. To learn about other important principles in CNC machine maintenance, read our article on this matter.CNC machine calibration steps
In order to significantly increase the accuracy of your operation, you need to go through the following steps to calibrate it:
Leveling the base
If you have moved or recently installed the device, you must level its bases. If the bottom surface of the CNC machine is uneven, the rails, bearings and other parts of the machine will experience excessive stress, and you may even need to replace tools and parts in the long run. To calibrate the CNC machine and align its bases, you can use laser leveling devices that will help you create a level plane for installation. You can also use the installation and commissioning services of CNC machine in Enginic.Set axes
In the second stage of CNC machine calibration, you must adjust the axes; For this, you need to adjust the fixed and movable tables and set the pointers to zero. Be careful that in this case, you have to align the fixed axes with respect to the moving ones so that they collide in the right place during work. The more the number of machine axes, the more carefully this step must be done and the more time it will take.
CNC controller calibration
The third stage of CNC machine calibration is related to its controller; Since the controller works based on a series of software codes and commands the hardware, it needs to be calibrated very carefully. In this case, you should adjust the movements of the spindle and axes well and update the controller codes if needed.In this case, you can also use the CNC controller repair service at Enginic.
CNC machine calibration tools
In order to be able to perform the calibration of the CNC machine accurately, you need to know the special tools for this work, some of which are:
Vibration measurement
The vibration measurement tool is one of the most important tools in calibrating CNC machines, which can detect vibration well and determine the performance of the spindle, motor, and the alignment of the bases. This device is able to detect the weakest vibration signals and show the exact amount and location of the vibration on the screen.Infrared thermometer
The infrared thermometer is another tool that can measure the surface temperature of the machining part and determine whether the wear rate of the machine is appropriate or not. According to the way of detecting the radiations, this thermometer is divided into two types, photoelectric and thermal, and it can detect which parts of the device heat up very quickly. As a result, it will greatly help to maintain the health of the spindle bearing and electrical connections.
Accuracy measurement tool
One of the main applications of CNC machine calibration is related to improving its accuracy, for which laser interferometers are used. These interferometers can accurately determine the position and geometry of rails and CNC tools and determine the accuracy of the machine in linear and angular positioning, perpendicularity and parallelism, flatness, etc.The use of these tools will eventually lead to the calibration of coordinates and inputs or outputs and can significantly increase the efficiency of the device.
final word
If you want your CNC machine to work without problems for a long time, you must perform the calibration of the CNC machine in regular and accurate periods.
